Purple fluorite with rich aggregate of lustrous, prismatic gray/blue celestite. The Lower-Rosiclare level was the first location in the mine to produce celestite. It is rare to find choice specimens from this horizon since the level was an intermediate producer situated more or less halfway between the Rosiclare and Sub-Rosiclare horizons. Advance mining ca. 1985. Excellent condition. Plavac Minerals from Lois Shriver Collection. Entered into Ross C. Lillie database as RCL2613.
